Thermistor is a kind of sensitive elements. According to different temperature coefficients, thermistor can be divided into positive temperature coefficient thermistor (PTC thermistor) and negative temperature coefficient thermistor ( NTC thermistor ). The typical characteristic of thermistor is temperature sensitive. With temperature increasing, the PTC thermistor resistance will increase and the NTC thermistor resistance will decrease. PTC thermistor and NTC thermistor both belongs to semicond...(more)
Based on Peltier effect, thermoelectric cooler (TEC) is built, which can both heat and cool, depending on the direction of DC current. TEC is a heat transfer tool. It has many advantages such as no refrigerant, high precision temperature control, compact size and so on. TEC has been widely used for temperature control of laser system temperature, refrigeration, water heater, air conditioner and computer CPU, etc. The working state of TEC is based on the current direction and size. In order to re...(more)
SMT Inductor Kits are designed for electronic designers in collecting and organizing surface mount inductors. We have a few types of inductor kits, which contain different inductors of commonly used values, with different quantities. These inductor kits offer a simplest way for obtaining any value of inductors within the shortest time with the highest efficiency. There are 128 individual compartments inside the inductor kits. Each compartment holds a certain amount of inductors of a certain valu...(more)
Thermistor with negative temperature coefficient is called NTC thermistor . NTC thermistor is made of such metal oxide materials as manganese, cobalt, nickel and copper, etc., with semiconductor. NTC thermistor has compact size, resistance and temperature characteristics with small fluctuations, etc. As NTC thermistor has fast response to all kinds of temperature changes, it can be used to realize high sensitivity and high precision detection. Some thermistor with positive temperature coefficien...(more)
We are introducing an easy and convenient way to organize and sort out SMT inductors. Tiny and precise SMT components like SMT inductors, resistors and capacitors, are very common in electronic designers bench, but its hard to organize them in a small place. In order to save time and space, ATI provides a smart way for this: Super Surface Mount Inductor Kits . These inductor kits contain various values and quantities of inductors, which come from renowned inductor manufacturer, such as TDK, Viki...(more)
Glass sealed NTC thermistor is a kind of NTC thermistors, which is mainly used for temperature compensation. The main features of glass sealed NTC thermistor is high reliability, high stability, compact size, light weight, high temperature resistance and moisture resistance, but its response time is little longer. Whats more, this NTC thermistor has high accuracy of measurement and wide range of temperature. It is very convenient to be installed on PCB. Because of the glass wrapping, this NTC th...(more)
Continued from the article Peltier Controller Evaluation board TECEV104 (I). In order to better understand this Peltier controller evaluation board, lets get more information about the board. A tuning circuit and an application circuit constitute this Peltier controller evaluation board. This evaluation board can set the output voltage limit, tune the compensation network, set internal operating temperature point, and has an LED for indicating the temperature status of the Peltier controller . T...(more)
Thermistor is a kind of sensitive elements. According to different temperature coefficient, thermistor can be mainly divided into two types, positive temperature coefficient (PTC) thermistor and negative temperature coefficient (NTC) thermistor . With the increase of temperature, the resistance of PTC thermistor will increase, and the resistance of NTC thermistor will decrease. PTC thermistor and NTC thermistor both belong to semiconductor devices. The main characteristics of thermistor are high...(more)
